The Fix-It Playbook — How to Clear a Clogged AC Drain Line | 6-Page PDF | 2026 Edition

A clogged condensate drain either shuts your AC off or leaks through the ceiling. Clearing it is a 15-minute job with a shop vac and a jug of vinegar.

Inside: Why this is the leak you don't see coming · The honest cost comparison · Step 1: Know your drain system · Step 2: Signs you've got a clog · When to stop and call a pro instead · What you'll need · Troubleshooting · What the repair tech won't tell you.

Doing it yourself: about $0–10. Vinegar and a shop vac you likely already own. Calling a pro: $100–200 for a service call to suck out a clog and pour vinegar.

6 pages of labeled diagrams, parts lists and real numbers — no filler, no 40-minute video. Instant PDF download: print it for the garage or follow it on your phone with the parts in hand. Yours to keep, no subscription.
